oLovER SEED HULLER AND scAmrIEa Application filed April 20,

This invention relates to seed hulling and scarifying machines, an object being to provide a machine which is especially adapted for hulling and scarifying clover seed, and

for separating the hulls from the seed so Ythat the latter will be in proper condition for rapid germination when planted.

Another object of the invention is the provision of a machine of the above character l0 whose casing is divided into a hulling and scarifying compartment and a compression compartment,.so .that the seed in addition to being acted upon by a beater in the hulling and scarifying compartment will be also acted upon byvair furnished by a force fan within the compression compartment, where the air is-compressed to be expanded as it enters the hulling and scarifying compartment and thus assist in agitating the seed 9C' hulls to carry off the dustand hulls from the machine.

Another object of the invention of the provision of a hulling and scarifying surface of novel construction which acts upon the 27' seed to remove the hulls and to scarify and i prepare the seed for the purpose aboveY stat- Nith the above and other objects in View,v the invention further includes the following 3f novel features and 'details of construction, to

be hereinafter more fully described, illustra'ted in the accompanying 'drawings and pointed out in the appended claim. In' the drawings: r Figure 1 is a longitudinal sectional view of a machine constructed in accordance with the invention. Y' Figures 2 and 8 are sections taken respectively on the lines 2-2 and 3 3 of Fig-- Referringto the drawings in'detail wherein like characters of reference denote correspending parts, the machine comprises a casing which is circular in cross section and formed of a pair of frusto conical sections 10 and 11 which are connected at their small; er ends. The construction provides a combined hullingand scarifying compartment 12 and a compression compartment 13, the compartment 12 being of greater length than 192s. serial No. 271,584.

the compartment 13 while communication is established f between these compartments through the restricted portion 141 of the casing. Theouter end of the'compartment 12 is'55f closed as indicated at 15 while the outer end ofthe compartment 13 is provided With a foraminous wall 16 of any suitable material.

Extending longitudinally through the ma- A chine is a shaft 17 and secured upon'this 60' shaft is a hollow beater 18. This beater is located Within the compartment 12 and is of frusto-conical shape and is spaced from thev wall of the compartment 12. The beater is provided with a cover 19 while the 65 compartment 12 is provided with a lining 20 which is spaced from and opposed tothe cover 19. The cover 19 and lining 20 are of like construction', being formed of sheet' metal having openings punched ltherethroughV with thematerial around these openings extending outward so that a grater-like surface is provided. The casing Vand thebeater however are "formed of imperfo'v rate material. The beater 18 is also pro'- 75 4 kvidedwith spaced beaterv blades 21 which are preferably slightly inclined with respect tothe longitudinal center-of the beater.

Also mounted upon theshaft 17 is a. force fan 22.V This fan is located at the outer y or large `end of the compression chamber 13 and mounted upon the shaft 17 upon the'outside of `the casing is a pulley 23. AThis pulley is driven byfmeans of a belt 24 from a pulley 25 which7 iis mounted upon the sha-ft of a 85 motor 26,1.- Y p Mounted upon the casing is a feed hopper 27, a chute 28 extending from the lower end of this hopper intothe chamber 12 so that seed" placed vwithin this hopper may be fed into'the chamber to vbe acted upon by the beater and the lining 20. A slide 29,0011- trols the feed of seed to the machine.

Extendingrfrom vthe larger end of the compartmentf12 is a pipe or conduit 30 which also communicates with the compartment 12 through a branch pipe 31. The pipes 30 and V31 are designed to carry oft' dust, hulls, etc. from the compartment 12 10Q While seed is discharged from the comparte ment through a discharge spout 32.

The beater 18 is rotated through the oper*V ation of the motor 26 and seed fed into the compartment 12 from the hopper 27 will be taken up by the graterlike cover 19 of the beater and thrown against the grater-like lining l 20 of the compartment 12. The blades 21 will also take up the seed and throw them against the lining 20 With increased force, so that the hulls will be broken and removed from the seed. When using the machine simply as a scarifier, the blades 21 may be removed.y

The fan 22 forces air from the chamber 13 to the chamber 12 and asthe air passes from the chamber 13 at the restricted end, the air will be compressed and will pass into the chamber 12 through the restricted portion 1%, expanding as it passes through this chamber. The force of this air will assist invagitating the seed and Will carry oil the dust and hulls through the pipes 20 and 31, u-'hile `the seed will pass out through the `discharge spout 32.

The `invention is susceptible of various chan es in its form,` proportions and minor detai s of construction and the right is herein reserved to make such changes as properly fall Within the scope of the appended elaim.

Having described the invention what is claimed is A clover seed huller and seariier comprising aV casing having its opposite end p0r-V tions cone-shaped, the smaller ends of said coneshaped portions being joined together, one of the said end portions being open at its outer end, a vertical Wall closing the outer end of the other portion,` a fan located v in the open outer end of one of said portions and yadapted to discharge a blst of air through the smaller ends of thel cone-Shaped. portion into the portion having the closed outer end, a cone-,shaped beater journaled for rotation in that end portion of the cas;-v

ing having the closed outer end and the larger end of said beater being spaced from the outer end Wall of said portion, a hopper having a discharge outlet located above the` smaller end of the beater, the casing having gust outlet passage-Ways located abovel the larger end of the beater and the casing having a seed outlet opening located below the larger end of the beater and at. the lower edge of the end closure Wall of that end portion oi"- the casing in which the'beater is located.

In testimony whereof' I aahx my signature.
